Gen NCLEX (NGN) style case studies to help you apply clinical judgment and secure a high
grade on your proctored final.
Question 1: Respiratory Pathophysiology
A 58-year-old male with a history of smoking presents with a persistent cough and
significant mucus production for the past three winters. He is most likely suffering from:
A. Emphysema
B. Chronic Bronchitis
C. Acute Pneumonia
D. Pulmonary Fibrosis
Answer: B. Chronic Bronchitis
Rationale: Chronic bronchitis is clinically defined by a productive cough lasting at least
three months per year for two consecutive years, primarily caused by inspired irritants
that increase mucus production.
Question 2: Neurology
Which neurotransmitter deficiency is the primary hallmark of Alzheimer’s Disease?
A. Dopamine
B. Serotonin
C. Acetylcholine
D. Norepinephrine
Answer: C. Acetylcholine
Rationale: The loss of cholinergic neurons and a decrease in acetylcholine in the
cerebral cortex and hippocampus are major factors in the cognitive decline seen in
Alzheimer’s.
,Question 3: Renal System
What is the most common clinical manifestation of nephritic syndrome?
A. Massive edema
B. Hematuria with red blood cell casts
C. Hypotension
D. Clear, diluted urine
Answer: B. Hematuria with red blood cell casts
Rationale: Nephritic syndrome is characterized by inflammatory injury to the glomerulus,
allowing red blood cells to leak into the urine, often resulting in "cola-colored" urine.
Question 4: Cardiovascular System
A patient is diagnosed with stable angina. The nurse understands that this chest pain is
typically:
A. Unpredictable and occurs at rest.
B. Relieved by rest and nitroglycerin.
C. Caused by a total coronary artery occlusion.
D. Associated with ST-segment elevation on EKG.
Answer: B. Relieved by rest and nitroglycerin.
Rationale: Stable angina is caused by fixed atherosclerotic plaques; pain occurs when
myocardial oxygen demand exceeds supply (exertion) and resolves when demand
decreases (rest).
Question 5: Endocrine System
Which condition is characterized by an overproduction of growth hormone in an adult
after the epiphyseal plates have closed?
A. Gigantism
B. Acromegaly
C. Cushing’s Disease
D. Myxedema
Answer: B. Acromegaly
Rationale: Gigantism occurs if the GH excess happens in childhood; acromegaly occurs
in adults, leading to the enlargement of small bones (hands/feet) and facial features.
,Question 6: Hematology
What is the primary physiological defect in Iron Deficiency Anemia?
A. Reduced absorption of Vitamin B12
B. Failure of the bone marrow stem cells
C. Decreased synthesis of hemoglobin
D. Rapid destruction of red blood cells
Answer: C. Decreased synthesis of hemoglobin
Rationale: Iron is a necessary component of the heme group in hemoglobin; without it,
the body cannot produce enough hemoglobin, resulting in microcytic-hypochromic cells.
Question 7: Gastrointestinal System
The development of a "telescoping" of one part of the intestine into another is known as:
A. Volvulus
B. Intussusception
C. Herniation
D. Adhesion
Answer: B. Intussusception
Rationale: Intussusception causes bowel obstruction and can lead to ischemia; it is
most common in infants but can occur in adults due to tumors.
Question 8: Fluid and Electrolytes
A patient with chronic alcoholism is at high risk for which electrolyte imbalance that can
lead to torsades de pointes?
A. Hypercalcemia
B. Hypomagnesemia
C. Hypernatremia
D. Hypoglycemia
Answer: B. Hypomagnesemia
Rationale: Magnesium deficiency is common in chronic alcohol use and is a well-known
cause of dangerous ventricular arrhythmias like torsades de pointes.
, Question 9: Cardiovascular System
What is the primary cause of the "silent killer," essential hypertension?
A. Renal artery stenosis
B. Adrenal tumor
C. Idiopathic (unknown)
D. High salt intake alone
Answer: C. Idiopathic (unknown)
Rationale: Primary (essential) hypertension accounts for 90–95% of cases and has no
single identifiable cause, though genetics and lifestyle play major roles.
Question 10: Reproductive System
Which hormone is primarily responsible for the growth of the endometrial lining during
the follicular phase of the menstrual cycle?
A. Progesterone
B. Estrogen
C. Luteinizing Hormone (LH)
D. Oxytocin
Answer: B. Estrogen
Rationale: Estrogen dominates the proliferative phase, rebuilding the endometrial lining
after menstruation.
Question 11: Immunology
In Systemic Lupus Erythematosus (SLE), the type of hypersensitivity involved is:
A. Type I (Immediate)
B. Type II (Antibody-mediated)
C. Type III (Immune complex)
D. Type IV (Cell-mediated)
Answer: C. Type III (Immune complex)
Rationale: SLE involves the formation of antigen-antibody complexes that deposit in
tissues (like the kidneys and joints), triggering inflammation.
